Things you need to do once
- Ensure you and your haulier or intermediary are registered with the Trader Support Service (TSS). Further guidance can be found in the Registration: Step-by-step guide to using TSS guide on NICTA.
- Apply for the UK Internal Market Scheme (UKIMS) and upload your authorisation to your TSS Company Profile. For guidance on how to upload your authorisation, see How to use the TSS Portal on NICTA.
- If you move prepackaged retail food and drink for final consumption in Northern Ireland (NI), register for the Northern Ireland Retail Movement Scheme (NIRMS) and upload your authorisation to your TSS Company profile. For guidance on how to upload your authorisation, see How to use the TSS Portal on NICTA.
- If you are using a haulier/intermediary, you will need to grant them permission to use your UKIMS authorisation and Trader Goods Profile (TGP) (if you have one) to submit an Internal Market Movement Information (IMMI) on your behalf. You can do this on your TSS Company Profile. You can change or revoke access permissions to your UKIMS and/or TGP at any time.
- You can check the status of your UKIMS, NIRMS and TGP using the Windsor Framework Trader Readiness Questionnaire in your TSS Company Profile. For guidance on how to complete the questionnaire, see How to use the TSS Portal on NICTA.
Things you need to do for every movement
- Determine if the goods are eligible to move using the simplified processes for Internal Market Movements and inform your haulier. See the Conditions for using the simplified processes section.
- Decide if IMMI is to be submitted:
- Pre-movement by you or your haulier/intermediary OR
- Post-movement by you or your agent/intermediary
- Note: See the Internal Market Movement options in the TSS section
Pre-movement
- If you are submitting the IMMI, provide your haulier/intermediary with the Local Reference Number (LRN) of the IMMI. OR if your haulier/intermediary is submitting the IMMI on your behalf, you will need to provide them with the information to complete it.
- You or your haulier/intermediary will need to submit the IMMI, through the TSS Portal at least two hours before the goods are due to arrive in NI.
Post-movement
- If you decide to submit the IMMI post-movement, you will need to give the haulier/intermediary the correct EORI number aligned with your UKIMS authorisation to use in the Importer EORI field on the Entry Summary Declaration.

- The NIRMS authorisation (if the trader has one and is moving a NIRMS-applicable commodity code)
- The name and address of EORI holders (provided they have a TSS account not set to private)
- Procedure code 4000, for traders who have specified that they do not move goods into a customs or excise warehouse on their TSS Company Profile
- A recommended Additional Procedure Code, based on the commodity code entered or populated through the TGP; the recommended Additional Procedure Code must still be checked
- The Document References related to the trader’s authorisations
- The Document Codes related to the type of transport
- Additional Information Codes NIDOM & NIREM
TSS will categorise the goods and recommend an Additional Procedure Code to use on the IMMI.
TSS will allow you to use the HMRC TGP directly in the TSS Portal (if you have signed up for it)
TSS will allow you to create, edit and delete TGP entries directly in the TSS Portal (if you have authorised TSS to access your TGP)
What the TGP will do
Using the TGP in TSS will auto-populate the following information onto the IMMI:
- The commodity code
- The country of origin
- The category of the goods
- Additional Information codes (if present on the entry)
- Document References and authorisations (for example, a NIRMS authorisation if present on the entry)
Internal Market Movement options available in the TSS
Pre-movement
- Pre-movement IMMI – an Entry Summary Declaration, combined with the IMMI completed as a single submission before the goods are due to arrive.
- Pre-lodged standalone IMMI – where the haulier has completed an Entry Summary Declaration outside of TSS, or where an Entry Summary Declaration only has been submitted, and a standalone IMMI is completed before the goods are due to arrive.
Post-movement
- Post-Movement IMMI – TSS allows traders, as part of the TSS Simplified Procedure, to convert the generated Supplementary Declaration into the IMMI if goods meet the criteria for using the simplified processes. This conversion significantly reduces the information fields requiring completion.
- Arrived Standalone IMMI – this is for traders looking to release goods for free circulation (also known as diversions) that have been previously placed under customs special procedure on their arrival in NI and meet the requirements to use the simplified processes.
What are the simplified processes for Internal Market Movements?
The simplified processes for Internal Market Movements contain a range of facilitations to ease the process of moving ‘not at risk’ goods (parcels and freight) from a business in Great Britain (GB) to a business in NI.
The UKIMS is a trusted trader authorisation and is a mandatory requirement to use the simplified processes. It allows traders to declare goods ‘not at risk’ if they are brought into NI for sale or final use by end consumers in NI and meet all the other criteria to move under the UKIMS, as set out in the guidance in Apply for authorisation for the UK Internal market Scheme if you bring goods into Northern Ireland on GOV.UK.
The simplified processes include:
- The IMMI, which is a simplified dataset for GB-NI movements, available to traders who are UKIMS authorised, where the goods are for sale to or for final use by an end consumer in NI.
- The TGP – an online service from HMRC for traders that holds records about goods movements to NI from GB, which is available on the TSS Portal. The information in the TGP can be used to auto-populate information onto the IMMI.
- A new Entry in Declarant’s Records (EIDR) authorisation, available to the UKIMS-authorised traders, known as the UKIMS-EIDR. The UKIMS-authorised traders will be able to apply for a new HMRC authorisation for EIDR, specifically for use on internal market movements. For further details on the UKIMS-EIDR and when it can be used, see Apply to make an entry declaration in your records under the UK Internal Market Scheme on GOV.UK. Although not available in TSS, traders can continue to use their existing EIDR authorisation (if they have one) in the TSS Portal.
Conditions for using the simplified processes
- The Importer of Record must have a UKIMS authorisation.
- Goods must be ‘not at risk’ of entering the European Union (EU).
- Goods must be moved by direct transport from GB to NI (including transit goods, providing the transit starts in GB and ends in NI).
- The goods must be in free circulation in GB prior to movement.
- Goods must not be Category 1 Goods (those liable to quotas, anti-dumping duties or trade safeguards and those subject to prohibitions or restrictions). Details on Categorisation can be found on Categorising goods for Internal Market Movements on GOV.UK.
Which Goods Categories can move using the simplified processes?
- Standard Goods are all goods (excluding excise) that have no documentary controls and/or have no licensing requirements. Prepackaged retail food and drink goods moving under a NIRMS authorisation fall into this category.
- Category 2 Goods are subject to special health, licensing or environmental controls, including excise goods. Goods moving under the Northern Ireland Plant Health Label (NIPHL) scheme fall into this category.
Is an Entry Summary Declaration required for the movement of goods using the simplified processes?
An Entry Summary Declaration is always required for goods moved from GB to NI pre-movement. Further information on Entry Summary Declarations can be found in the ENS Step-by-step Guide: Standard Process and Consignment First Process on NICTA.
